Brown Bats’ Habits

Roosting Behavior and Preferences:

Brown bats have diverse roosting behaviour and exhibit a preference for various structures in Ontario. While they naturally gravitate towards caves and trees, urban environments offer alternative roosting opportunities. Buildings, attics, and even chimneys provide warm and secure spaces for these bats to establish colonies.

Migration Behavior:

Brown bats in Ontario display migratory behaviour, with some individuals travelling vast distances in search of suitable hibernation sites. During the fall, they gather in maternity colonies to mate and give birth, forming tight-knit social groups. As temperatures drop, these bats embark on long journeys to caves and protected areas where they enter a state of torpor to conserve energy during winter months.

Hibernation Habits:

Hibernation is a crucial period in the life of a brown bat. To survive the harsh Ontario winters, they seek shelter in caves, mines, and other secluded locations. During hibernation, their metabolic rate drops significantly, allowing them to conserve energy. It is essential to be mindful of these hibernation sites and to avoid disturbing them to ensure the bat’s survival and overall ecosystem balance.

Dietary Habits and Choices

Brown bats are insectivorous creatures, making them invaluable for natural pest control. Every night, they emerge from their roosts to feed on a wide range of flying insects, including mosquitoes, moths, and beetles. Their hunting technique, known as echolocation, involves emitting high-pitched sounds and interpreting the echoes to locate and capture prey. By consuming vast numbers of insects each night, brown bats play a vital role in maintaining ecological balance.

Sleep Habits

As nocturnal creatures, brown bats sleep during daylight hours to conserve energy for their nightly foraging activities. During their sleep, they often hang upside-down from their roosting sites, using their feet and claws to maintain a secure grip. Observing their sleep habits can be a fascinating sight, as they appear peaceful and undisturbed even while hanging upside-down.

The Importance of Removing Brown Bats from Our Homes

Disease Carriers: Brown bats, like all mammals, can carry diseases, including histoplasmosis. The fungus responsible for histoplasmosis is found in the droppings of brown bats and can pose health risks to humans if inhaled. Taking prompt action to remove bat colonies from your home is essential to minimize this potential health threat.

Home Damage: Brown bats can cause significant damage to homes. Their droppings, called guano, can accumulate over time, leading to unpleasant odours, staining, and potential structural damage. Additionally, the accumulation of guano can attract other pests, such as beetles and cockroaches. Timely removal of bat colonies from your home can help protect your property and ensure its structural integrity.

Protection as a Species: It is vital to remember that brown bats are a protected species in Ontario. Causing harm to bats or their habitats is illegal.
